CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 265,561, dated October 10, 1882.

Application tiled May 26, 1882.

To all whom it may concern:

Be it -known that I, IRVING BARKER, of Joliet, in Will county, and State of 1llinois, have invented certain new and useful Improvements in Oar-Trucks, the construction and operation ot' which l will proceed to exlplain, reference being had to the lannexed drawings and the letters and figures thereon, in which- Figure l is a perspective View; Fig. 2, a plan view on the top of the truck without the box being on, and Fig. 3 a vertical central sectional view through a single pair. ot' boxes.

The nature and object of this invention consist in a novel construction of the truck-frame and arrangement of the Wheels and axles, and in the manner ot' oiling the journals, the truck being intended more particularly for a coalcar, and so arranged that it can be made to dump its load by simply ruiming aga-inst a stop or obstruction.

In the drawings, P P represent the frame of the truck, consistingofa bed-plate ofsome considera-ble width, so that the journal-boxes of the axles K may be quite long, so as to prevent any diagonal wrenching of the frame. Each Wheel is provided with a separate axle, as shown, extending across the car, so that it it has a journal in each bed-plate P, which causes one wheel to set a little ahead of the opposite wheelperhaps from two to four inches in a full-sized truck. By such a pair of Wide bed-plates being used no other frame is necessary.

ln crder to oil the journals, and to furnish means to carry a quant-ity of oil tolast a considerable time., each bed-plate is provided at the journals with a cistern, D, into which a quantity of oilis put, as shown at H, Fig. 3, to a line about even with the top of thejournalbox, just so it will not spill into the oil-holes o when the car is at rest. These cisterns are iilled by means of the tubes c, Fig. l, attached to the outside of the box B, and leading to said cisterns by means of a hole made through the corner of the box, as shown. These tubes are covered at their upper ends by a iiap attached to the side ofthe box B, so it will fall over the ends of the said tubes to keep out foreign sub- (No model.)

stances. The box B sets on the top ofthe bedplates P in such manner as to be tight to them, so the oil cannot spill out ofthe cisterns, and is bolted down by means ot' bolts passing up through the holes e and c. The box Bis also bound by the strong metal bands c2, the bedplates being notched at a4 to admit the middle band, as shown. to the truck, as aforesaid, and as shown in Fig. 1, the oil is poured into the cisterns from the tubes or spouts c, when the car is ready for use. The Wheels are set so near the middle of the truck that when it is desired to dump the load from the box the car is run against an obstruction xed upon the track, so the car will tip up forward in the position shown by the dotted lines in Fig. 3. By this means the car is not only relieved of its load, but the oil in the cisterns D is thrown forward, so it will rush over the journal-boxes and till vthe oil-holes o each time the car is dumped, thus saving much time in oiling the car-journals, rendering them seit'- oiling, and forming a durable, economical, and efficient car-truck, for the purpose for which it is intended. By this arrangement ot' having the wheels fastened rigidly to the axles the Wheels must run true on the track, and it also permits the car to turn a very short curve without causing any wheel to drag on the i'ail, and, further, the car frame or truck cannot sag down in the center.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows, to Wit:

In a car-truck, the bed-plates P, having the axle-boxes containing the Oilchambers D on either side ofthe axle, and arranged to oil the axle by tilting the car, in combination with the Wheels a2, having their axles K extending across the car, and box B, provided at its outer side with the oiling-pipes c, and secured tothe bed-plates P, to form an oil-tight cover to the axle-boxes, all arranged to operate in the manner and for the purpose set forth.
